The invention relates to railway car doors and .door openings and more particularly to the weather-proong of the same.

Numerous weather-stripping devices and other arrangements have been proposed for preventing 'the passage of moisture, sparks, and dirt around -the edges of ca'r doors-to the interior of the car.

body. Some arrangements involve yielding ele;-

ments which may not retain their elasticity cr 'may not coact properly with opposing elements for reasons similar to those pointed outl aboveA Some arrangements, although adapted for frontv and rear door-edges, where the movement of the door and body elements is towards and away from each other, are not suitable for top and bottom door edges where the door andbody elementsV must move along each other.

The main object of the present invention is to prevent the passage oi air currents, dirt, etc. to

` the interior of the car by construction which is 'free of the disadvantages attending earlier weather-stripping, etc. Preferably the object is.

attained by providing a plurality of pockets ar-v l requiring yielding characteristics.

An additional object of the invention is to effect a satisfactory drainage outwardly of the car of matter trapped by'the airpockets.

(ci. 1ct-1s) a modified form of pocket structure of the side plate and door sill. a

Figures 5, 6, 7,' and 8 correspond .to the 'lower portions of Figures 3 and 4 but illustrate diierent modincations of the door sill pocket structure;

Figures 9, 10, and 11 correspondto Figure 2 but illustrate modications of the front and rear door post and door edging pocket structure.

Figures 12 and 13 illustrate other rear door post and pocket sections; f l

Figures 14 and 15 correspond to the upper portions of Figures 3 and 4 but illustrate modiiica` tions of the pocket structure provided by the plate and door top edging.

'Ihe car framing includes side sills I, side plates 2, door front posts 3, door rear posts side walls 5, vand oor 6, all of which may be of any familiar type either steel, or wood, or composite structure. The framing members dene a door'opening 1 and the sliding Idoor 8 is movable on ball bear ings 9 along track I0 to open and close the open ing. The details of the car framing, the door structure and its mounting are relatively unimportant except as they contribute to the prov vision of the weather-excluding pockets whici form the gist of the present invention.

Rear door post- An upright plate II forms the facing for the rear door post 4 and it extends outwardly beyond the e of the car and terminates in a ilange I2, exte ding rearwardly along side of the door panel plate I3, to form a threesided pocket I4 facing away from the door opening. A .second plate I 5, spaced longitudinally r" the car from plate I I projects outwardly from the side wallI and terminates in a flange I6, extending away from the opening 1 and alongside the door panel, to form another three-'sided pocket I1 facing away from the'door opening.

Pockets Il and I1 aredisposed in succession along the side of the car, and the .door panel i3 vcooperates with the pocket structure to substanmuy close the inner pocket I4. Preferably the door includes a rear frame or edging I8 having anextension I9 projecting inwardly from the plane of the panel I 3 and terminating in a forwardly extending ilan'ge 20 projecting into the outer pocket I1 to increase the efiiciency of the weather seal. It is desirable for elements I6 and' 2 0 to contact with each other but this is not necessary to eil'ect a satisfactory weather seal because ofthe successive or double pocket structure I1 and Il.v

An upright plate 2i is applied to the door front post 3, extends outwardly from the side of the car, and terminates in a ange 22 extending 55 longitudinally of the car away from the door opening 1 to form a three-sided pocket 23. Another plate 24 extends outwardly from the side of the car a short distance in front of plate 2| and terminates in a rearwardly and outwardly inclined flange 25 spaced outwardly from flange 22 on plate 2|. The door front frame or edging 26 includes a forwardly directed flange 21 positioned to project into the space between anges 22 and 25 and to abut plate 24 to limit the forward closing movement of the door. Member 26 .and ange 21 form an outer pocket 28 serving to break up any air currents and to trap any dirt, sparks, etc. tending to pass around the front edge of the door. If contact between flange 21 and plate 24 is poor, then the secondary pocket 23 similarly interrupts passage into the car of air and undesirable matter carried thereby.

At the bottom of the door opening, threshold structure is provided above and extending outwardly from the side sill and includes a hanger 30 and a one-piece member 29 having an upper horizontal flange for the threshold plate and a lower horizontal flange with depending edge for guiding the door and forming a retaining element 3|. The door bottom frame or edging 32 has an extension 33 projecting under the lower edge of element 3| and terminating in an upwardly directed flange 34 extending alongside of and inwardly of element 3|.

This construction provides an outer pocket 35 and inner pockets 36 and 31 which function as do the double or successive pockets previously described.

At the top of the door opening, a door retainer 38 extends outwardly from side plate 2 and terminates in a downwardly projecting flange 39. A pocket-forming member 40 extends downwardly from the horizontal leg of member 38 at a point spaced inwardly from flange 39. The door top frame or edging 4| extends upwardly between elements 39 and 40 and terminates in an outwardly and a downwardly projecting elementI 42 whereby an outer pocket 43 is provided between member 39 and the door structure, and an inner pocket 44 is provided between the door edging and the elements 38 and 40.

With the construction described, the door structure and elements on the side wall cooperate to form successive pockets providing a double trap for air, water, sparks, dirt, etc. tending to enter the car through crevices between the door and the car body. .Most of such matter Will'be trapped in the outer pocket, from which it may drain directly to the outside of the door. If any particles of matter do pass the outer pocket, they will be caught in the inner pocket where the velocity of the air currents, if any, is substantially reduced.

In the modification shown in Figure 4, a door bottom edging member 45 cooperates with a door track 46 to form an outer pocket 41, and the downwardly and forwardly inclined flange 48 on the threshold plate cooperates with the door track member to form an inner pocket 49. The double pocket at the top of the door opening corresponds closely to that shown in Figure 3 but the terminal portion 50 of the door top edging .is an integral extension of the Z-bar ange and is arcuate in form instead of being angular as is the member 42 shown in Figure 3. Element 50 cooperates with the retainerg5| and a depending element 52 thereon to form inner and outer pockets 53 and 54.

In Figure 5, the door lower edging elements 55 and 56 cooperate with the door track 51 and with the threshold support 58 to form an outer pocket 59 and an inner pocket 60. Preferably a slight space is provided between flange 6| on member 58 and the opposing face of track 51 whereby moisture, etc. penetrating into pocket 60 may drain therefrom. The space 60a may be considered another inner pocket.

In Figure 6, the door track 62 is spaced substantially from the threshold support 63 and the door inner edging element 64 extends downwardly inside of track 62 and adjacent to a vertical web 65 on member 63, the lower edge of which is flanged outwardly whereby an outer pocket 66 is formed. The upper portion of member 63 and the inner face of the door edging and lower portion of the door panel and the outer portion of the threshold plate 61 form an inner pocket 68.

Figure 7 illustrates a similar construction in which the threshold support 69 is anangle and the lower pocket-forming element 10 on the body of the car is a separate element but cooperates with the side sill structure andthe door edging and other parts to form the outer pocket 1| and the inner pocket 12 corresponding to pockets 66 and 68 in Figure 6.

In Figure 8, the outer pocket 13 is formed by the lower angular portion of the door edging 14 and the adjacent side sill, and an inner pocket 15 is formed by the door edging and a horizontal element 16 on the threshold support member. Another inner pocket 11 is formed between element 16 and the threshold 18.

In Figure 9, the front and rear door posts and 8|, respectively, 'are formed of Z-bars having their outer iianges 82 and 83 projecting outwardly from the side of the car. Pocket-forming elements 84 and 85 extend outwardly from the side of the car at points spaced forwardly and rearwardly, respectively, of flanges 82 and 83, and the door panel and edging structures indicated at 86 and 81 cooperate with the door posts and elements 84 and 85 to form outer pockets 88 and 89 and inner pockets 90 and 9|. These structures correspond closely to that illustrated in Figure 2 except there is no longitudinal iiange on the outer edge of the member forming the face of the door opening. The inclination oi.' the. terminal ange on element makes for an elongated and closer gap between the same and the adjacent element of the door rear edging if they do not contact. y

Figure 10 illustrates a similar general arrangement but shows different stylesA of door posts 92 and 93, respectively, it being necessary to provide separate members 94 and 95 extending outwardly from the side of the car to cooperate with the door structure and the body members 96 and 91 to form the inner pockets 98. The outer pockets and the elements forming them are the same as in Figure 9, but the closing movement of the door isv shown as limited by the abutment of the elements at the rear of the door, the door and post irregularities providing a small gap between the front post and door edge.

In Figure l1, the front door post 99 includes as integral parts thereof both elements |00 and |0| extending outwardly from the side of the car and cooperating with each other and with the front door edging |02 to form the outer pocket |03 and the inner pocket |04. Similarly, the rear door post |05 includes as integral parts thereof both outwardly projecting elements |06 and |01 cooperating with each other and with Iform the outer pocket ||4 and the inner pocket Figure 13 corresponds closely to the rear post shown in Figure 11 but the element |26v on the post contributing to the outer pocket isfnot an integral partof the post.

-Figure 14 illustrates a modification of the pocket structure at the top of the door opening in which the door top edging terminates inra vertical flange IIB extending rearwardly of the depending flange I|1 on the retainer IIB. The top edging has a lateral flange I I9 projecting under element I I1 and towards the depending outer web of retainer, ||8. Outer ypocket |20 and inner pocket |2| thus provided are both located outwardly of the door panel |22.

In Figure 15, the outer web |23 of the door retainer is provided with a plurality of spaced inwardly projecting flanges |24 and the door edging is provided with a plurality of spaced outwardly extending anges |25; Flanges |24v and |25 are disposed alternately to form a tortuous passageway between the exterior and lthe interior of the car to lprevent the passage of air and extraneous matter.

While a number of different forms of vention have been illustrated, they all have a common feature of the pluralityofpocketbeing provided by the cooperatingelements on the door and body structure for the .purpose described.
